How do you tweak it and adjust it?

No problem.

I was researching various heat exchanges and their adaptability to the aquarium and found the evaporative cooler design to be most logical. Researching that I found a few on the market but as stated they use foam which to me seemed troubling so I decided to try something a little different.

I adjust it by paying around with various flow rates of air and water until I find something that seems to work best. The fans are controlled by a variable 3-12 volt adapter and the water with a ball valve. The cooler is fed by overflow from the skimmer so it doesn't require an extra pump. Only power it uses is from 4 low wattage computer fans. Uses less than 12 watts.

Thanks Greg, good to see you're happy. We'll have to get you to post some recent pics of your setup. It's been a while

good idea, but i bet you will be using alot of water, do you have an auto topoff?

Yes I have an ATO, direct RO hook up. Not sure how much water I use but water is cheap.

Do you get much salt creep from your design? I'm assuming the pics were fresh after install

been up and running for a month and no salt creep yet. It's likely to show up eventually but that's why the unit is designed to be easily removed and cleaned.
